基于流体力学与热力学对自然风压进行详细研究,从理论上分析自然风压形成的机理,从结构上分析影响其大小的因素,并对自然风压的影响因素进行深入研究。在合理假设的基础上,研究井筒空气柱温度的分布规律。通过对某矿井筒温度测量拟合其温度随深度变化的曲线并对其可靠有效性进行检验。 Based on the fluid mechanics and thermodynamics, the natural wind pressure is studied in detail. The formation mechanism of the natural wind pressure is theoretically analyzed. The factors influencing its size are analyzed structurally and the influencing factors of natural wind pressure are studied in depth. On the basis of reasonable assumptions, the distribution of wellbore air column temperature is studied. The curve of temperature change with depth was fitted to the temperature measurement of a wellbore and its reliability and validity were tested.
